Question
NO(g) + NO3(g) → 2 NO2(g)
rate = k[NO][NO3]
- The reaction represented above occurs in a single step that involves the collision between a particle of NO and a particle of NO3. A scientist correctly calculates the rate of collisions between NO and NO3 that have sufficient energy to overcome the activation energy. The observed reaction rate is only a small fraction of the calculated collision rate. Which of the following best explains the discrepancy?
A.
The energy of collisions between two reactant particles is frequently absorbed by collision with a third particle.
B.✓ Correct
The two reactant particles must collide with a particular orientation in order to react.
C.
The activation energy for a reaction is dependent on the concentrations of the reactant particles.
D.
The activation energy for a reaction is dependent on the temperature.
